Hello,
you can unpack an AppImage (Kdenlive) with the command:
./kdenlive-24.08.2-x86_64.AppImage --appimage-extract
Then a folder is created: squashfs-root
In this folder you can make changes (insert plugins).
Does anyone know how to pack this squashfs-root again?
I have found the solution. You have to install appimagetool and go to the folder where the this squashfs-root is locatet and then enter into the terminal:
appimagetool squashfs-root
It’s very simple and works perfectly!
